Then it's one of the MusicLab versions that LOTR referred to in the link in post #6.
Sorry, but we don't offer support for those versions, since they don't use the Gnutella network.

Most BS users here prefer to use the version mentioned here: BearShare has been sabotaged.

However, if you want to keep using the version that you have, see whether there's a 'help' or 'support' link on the main page of your BS.

Good luck
